In May, I came to a middle school in Jiangning District of Nanjing to start a month of internship.

The alarm clock at 6:30 every morning, the bus at 7:18, the school at 7:48, and the office at 6:00 every afternoon. If you only look at the surface, this repetitive and boring life is really easy to produce job burnout after a long time, but fortunately, you are facing a group of live people every day. These children, who are more energetic than I am, are also taking some childish, and slowly gestating independent personality. The future is promising, which gives me some hope.

My instructor has profound theoretical foundation and rich teaching experience. I have benefited a lot from following him and gained a lot in teacher skills, teaching design and other aspects. He emphasizes the cultivation of students' mathematical thinking, penetrates mathematical thinking methods, and is good at connecting with students' existing experience. He has some meaning of constructivism, and his mathematical classroom is often permeated with humanistic spirit.

In addition to the normal internship activities in the first day of junior high school, another task was assigned to make up for the students with learning difficulties in the third day of junior high school. The class I took was the one with the largest number of students with learning difficulties in the whole grade, up to 12 people. After two weeks of compensation, the number of students dropped to 8 after the examination of the model examination, and the effect of compensation was "slightly effective". In order to consolidate this hard won progress and achieve greater success, the leaders and teachers kindly invited me to continue to go to school to make up the difference after the internship ended on May 31, which was difficult to overcome.

When I practice at the front line of teaching, I feel more confused about the education in these years. Why is the current school education forced to abandon "punishment"? Teachers dare not discipline students?
